Description Vincent Danen 2011-05-09 13:15:32 EDT

It was discovered [1],[2] the the GNU Debugger (gdb) would load untrusted files from the current working directory when .debug_gdb_scripts was defined.  While this was a design decision, it is an insecure one and users who do not pre-inspect untrusted files may execute arbitrary code with their privileges.
